【 摘 要 】

In this paper, the studies of finding the failure location on a sample cable by using the multiple pulse reflection method and the fault on the results of the measurement have been examined. A pulse generator with amplitude of 12 V and pulse width from 20 ns to 2 us has been designed as a multiple pulse reflection meter. The velocity of reflection pulse is calibrated in embedded system. The SOPC system detects the reflection pulse and measures the time of N times reflection pulses, then judge the fault type and compute the fault distance with corrected speed of pulse developed for measurement of pulse reflection by means of pulse velocity correction and have been examined here.
